Job said those words. Why? Because God had just reminded him about His Creation! 

Are you feeling overwhelmed, daunted, threatened by anything in the Universe? Or do you feel at the mercy of injustice? Remember God's Handiwork! Make use of your senses: Gaze. Feel. Taste. Hear. Consider … and confess with Job, "You can do all things, and no purpose of Yours can be thwarted"

Put your Trust in the Lord and do as He says!
